I decided to have a go at making an ascension window, thought I could just make a new custom window then bring it up with show_window Custom.Ascensionclasshere which works. I used the Tag window as something to work from as I have very little knowledge in these areas.

I managed to get the ascension spells on the custom window, it was all showing up good and well, but I have no idea how to add a cooldown (nothing fancy, just like the normal tinting until ready on the standard UI). So I was wondering if anyone could point me in the right direction.
